It's (almost, there's some iommu stuff without significance) right above the drm_dev_put(). This is made possible by a preceeding patch which added a drmm_ cleanup action to drm_mode_config_init(), hence all we need to do to ensure that drm_mode_config_cleanup() is run on final drm_device cleanup is check the new error code for _init(). Aside: Another driver with a bit much devm_kzalloc, which should probably use drmm_kzalloc instead ... v2: Explain why this cleanup is possible (Laurent). v3: Jump out at the right label (Francesco) Cc: Francesco Lavra <francescolavra.fl@xxxxxxxxx> Cc: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx> Signed-off-by: Daniel Vetter <daniel.vetter@xxxxxxxxx> Cc: Sandy Huang <hjc@xxxxxxxxxxxxxx> Cc: "Heiko Stübner" <heiko@xxxxxxxxx> Cc: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx Cc: linux-rockchip@xxxxxxxxxxxxxxxxxxx --- drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 12 ++++-------- 1 file changed, 4 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_drv.c b/drivers/gpu/drm/rockchip/rockchip_drm_drv.c index 20ecb1508a22..9b2502f92018 100644 --- a/drivers/gpu/drm/rockchip/rockchip_drm_drv.c +++ b/drivers/gpu/drm/rockchip/rockchip_drm_drv.c @@ -135,7 +135,9 @@ static int rockchip_drm_bind(struct device *dev) if (ret) goto err_free; - drm_mode_config_init(drm_dev); + ret = drm_mode_config_init(drm_dev); + if (ret) + goto err_iommu_cleanup; rockchip_drm_mode_config_init(drm_dev); @@ -173,12 +175,9 @@ static int rockchip_drm_bind(struct device *dev) rockchip_drm_fbdev_fini(drm_dev); err_unbind_all: component_unbind_all(dev, drm_dev); -err_mode_config_cleanup: - drm_mode_config_cleanup(drm_dev); +err_iommu_cleanup: rockchip_iommu_cleanup(drm_dev); err_free: - drm_dev->dev_private = NULL; - dev_set_drvdata(dev, NULL); drm_dev_put(drm_dev); return ret; } @@ -194,11 +193,8 @@ static void rockchip_drm_unbind(struct device *dev) drm_atomic_helper_shutdown(drm_dev); component_unbind_all(dev, drm_dev); - drm_mode_config_cleanup(drm_dev); rockchip_iommu_cleanup(drm_dev); - drm_dev->dev_private = NULL; - dev_set_drvdata(dev, NULL); drm_dev_put(drm_dev); } -- 2.24.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
